Stop looking at the weather reports, we've made 15 trips to Jamaica and I learned that a long time ago. I used to look and look at the weather as a way of feeling "connected" or something, it really only depressed me because it predicted rain every day yet when we got there we always had beautiful weather. I gave up my weather checking habit years ago. If you do have rain it will be a short shower in the afternoon, it will still be warm and many people choose to remain outside. Otherwise go sit on your balcony or take a nap or whatever but stop fretting the weather. We've never had rain everyday in 15 trips and it won't be all day even if it does rain everyday.
